All packages, except for `cmd` and `internal`, have been moved into a new `v1` root package.
Old packages are kept for backwards-compatibility reasons. All contained code is replaced with simple type aliases and proxy functions to `v1` implementations.
Old packages default to the Rego v0 syntax, new `v1` packages default to the Rego v1 syntax.

This commit introduces a few major changes:
- (Breaking change) Limits now exist for maximum request body sizes.
- Buffers are preallocated for reading request bodies.
- Buffers are preallocated for decompressing request bodies.
- Gzip decoder instances are reused in a `sync.Pool` across requests.
The effect on garbage collection is dramatically fewer GC pauses, giving
a roughly 9% RPS improvement in load tests with gzipped request bodies.
For larger request sizes, the number of GC pauses is dramatically
reduced, although the peak pause time may increase by a few percent.
Implementation notes:
- The DecodingLimits handler enforces the max request body size both
through a Content-Length check, and a MaxBytesReader wrapper around
the payload.
- The DecodingLimits handler passes the gzip payload size limit down
using a context key.
